Patented Jan. 14, 1930 UNITED STATES PATENT OFFICE HENRY A. BROWN, OF CLEVELAND, OHIO coN'rAoroa HANGER Application filed July 9, 1928. Serial No. 291,332.

The object of my invention is to provide a trolley contactor or trolley pan with an adjustable contactor hanger which will allow a trolley wheel while traversing same to establish certain circuits while off an adjacent trolley wire, which will be alignable to the course of the trolley wheel at points which have heretofore given considerable trouble to those installing same. This and other objects are accomplished by my invention, a

rier along the line A, A of Fig. 1.

Throughout the various views of the drawing similar reference characters describe and designate the similar parts.

The trolley pan is attached to a trolley wire 5 2 of the usual kind by means of brackets, one

at each end which are attached to two insulator bars 4, 4, preferably wood. To these bars are attached contactor strips 4, 4 in a conventional manner to establish well known circuits.

Attached to bars 4, 4 are lugs 5, 5, from which extend threaded studs 6, 6, which project through elongated slots 7 of extended arms 8, 8 of bracket 8 with nuts 9, 9 for the purpose of adjusting the bars 4, 4, so that they can be placed in a substantially horizontal plane for contact with trolley wheel 10. Stud 8 engages bracket 8 and hanger 11 which is supported by single or a plurality of guy wires which are often of varying types and tensions.

Special attention is directed to the fact that trolley pans, in certain locations, are subjected to tilting by reason of the supporting guy wires, or pull-offs, being so tied in at the far ends that a substantially horizontal position for the trolley pan contact faces is very difficult, if not impossible, to procure. This is particularly true on locations embracing curves.

' It is well understood by those versed in the art that a marked tilting of these faces can cause false operation. To force these faces, without my adjustable feature, into a plane substantially parallel to that on which the electric car operates often causes excessive labor and inconvenience. With my improvements it is a very simple operation to raise or lower either of the contact faces 4*, 4

by means of screws 6, 6 and nuts 9, 9.

While I have shown and described one embodiment of my invention, I do not restrict myself thereto, as yariations are possible without departing from the spirit of same.

I claim 1. A trolley contactor with contact bars" and central supporting bracket provided with elongated slotted arms, adjustable means to connect and hold said bars to said central supporting bracket.

2. A trolley contactor with contact bars and central supporting bracket, provided with elongated slotted arms, adjustable means to connect and hold said bars to the arm of said central supporting bracket.

3. A trolley contactor Wlth'COIltELCD bars and central supporting bracket provided with elongated slotted arms, adjustable means to connect and hold said bars to said bracket, means in said bracket for connecting the same with a span wire.

4. A trolley contactor with contact bars and central supporting bracket provided with elongated slotted arms, adjustable means to connect and hold said bars to said arms of the supporting bracket, means in said bracket for connecting the same'with a span wire.

5. In combination with a trolley contactor having a supporting bracket and a plurality of independent insulated contact bars disposed for electrical contact with the periphery of a trolley wheel, means to independently adjust and secure said bars to said supporting bracket.

6. In combination with a trolley contactor having a supporting bracket provided with arms and a plurality ofv independent insulated contact bars disposed for electrical contact with the periphery of a trolley wheel,

means to independently adjust and secure said bars to said supporting bracket.

7. In combination with a trolley contactor havin a supporting bracket and a plurality of in ependent insulated contact bars disposed for electrical contact with theperiphery of a trolley wheel, means to independently adjust and secure said bars to said supporting bracket, means in said bracket for m connecting the same with a span wire.

8. In combination with atrolley contactor having a supporting bracket provided with arms and a plurality of independent insulated contact bars disposed for electrical con- 15 tact with the periphery of a trolley wheel,

means to independently adjust and secure said bars to said supporting bracket, means in said bracket for connecting the same with a span wire.

20, 9. In a trolley pan having inclined horizontal electrical conducting bars secured thereto and a supporting bracket, adjustable means to connect and hold said bars to said supporting bracket, said bars being disposed 25 for electricalcontact with the periphery of L the trolley wheel.

v 10. A trolley contactor having parallel flat strips with flat bottoms inclined at an angle to the horizontal and conducting bars 39 secured thereto and a supporting bracket, ad-

justable means to connect and hold said bars to said supporting bracket.

11. In a trolley contactor having parallel flat strips with flat bottoms inclined at an saangle to the horizontal and conducting bars secured thereto and a supporting bracket, ad justable means disposed adjacent the ends of said bars to connect and hold same to said supporting bracket.

40 12. In a trolley pan having flat inclined horizontal electrical conducting bars secured thereto and a supporting bracket, adjustable means to connect and hold said bars to said supporting bracket. 7.
